Changing Rainfall Drives Locally Asynchronous Reproduction of Tropical Birds via Modular Trophic Pathways

Global Change Biology, Volume 32, Issue 3, March 2026.
In low‐latitude mountains, we found insectivorous bird communities switched from breeding before to after the dry season at a threshold in dry‐season insects. Localized breeding season reversal of insectivores across wet‐to‐dry gradients magnified short‐term effects of drought and contrasted with the seasonal stability of nectar‐fruit consumers.
